Add Support for UFS Host Controller Interface (UFSHCI) for communicating with Universal Flash Storage (UFS) devices. The steps to initialize the host controller interface are the following: - Initiate the Host Controller Initialization process by writing to the Host controller enable register. - Configure the Host Controller base address registers by allocating a host memory space and related data structures. - Unipro link startup procedure - Check for connected device - Configure UFS host controller to process requests Also register this host controller as a SCSI host controller. Taken from Linux Kernel v5.2 (drivers/scsi/ufs/ufshcd.c) and ported to U-boot. Signed-off-by: Faiz Abbas <faiz_abbas@ti.com>
